Question

If a chemical accepted \(\mathrm{H}^{+}\) from the surrounding solution, the chemical would be a(n) a. base. b. acid. c. buffer. d. Both a and c are correct.

Short answer

a. base.

Step-by-step solution

Recall the definition of acids and bases

Acids are substances that release \(\mathrm{H}^{+}\) ions (protons) when dissolved in water, while bases are substances that accept \(\mathrm{H}^{+}\) ions (protons).

Recall the definition of a buffer

A buffer solution is a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid. It is used to maintain a specific pH level by accepting or donating protons as necessary.

Identify the correct answer

Based on the information in Step 1, the chemical that accepts \(\mathrm{H}^{+}\) ions (protons) from the surrounding solution must be a base. Therefore, the correct answer is: a. base.
